Product Overview
The PBDH1000 Differential Probe is a 1-GHz bandwidth, differential-input,
active probe that is used in combination with a digital oscilloscope that has a
YOKOGAWA probe interface (hereafter referred as digital oscilloscope with a
probe interface).
To use the probe, you simply connect it to a BNC input terminal on a digital
oscilloscope with a probe interface.
* For information about digital oscilloscopes with a probe interface, contact your
nearest YOKOGAWA dealer.
Features
• Allows direct observation of differential signals
• Common mode rejection capability
• Wide frequency bandwidth from DC to 1 GHz
• High input impedance (1 MΩ, approx. 1.1 pF between each input terminal
and ground)
• Able to receive power from a digital oscilloscope with a probe interface
• Allows a digital oscilloscope with a probe interface to automatically detect the
probe
• Comes with various attachments that can be changed according to the item
that you want to measure
• Compact and lightweight

Usage Precautions
WARNING
Use this probe only with YOKOGAWA’s oscilloscopes with probe interface.
Even with YOKOGAWA’s oscilloscopes, this probe can be used only
when specified as a connectable accessory. Also, use this probe only with
standard or optional accessories sold separately.
CAUTION
• This probe is designed to measure the voltage difference between two
points on the device under measurement. It does not electrically isolate
the device under measurement from the measuring instrument.
• When cleaning the probe, wipe with a piece of soft cloth to prevent
damaging the probe. Do not immerse the probe body in liquid. Do not
use abrasive cleaners or volatile solvents such as benzine on the probe.
French
AVERTISSEMENT
Utilisez la sonde uniquement avec les oscilloscopes de YOKOGAWA
avec interface de sonde. Même avec les oscilloscopes de YOKOGAWA,
la sonde ne peut être utilisée que si spécifiée comme accessoire
connectable. Et utilisez la sonde uniquement avec des accessoires
standard ou des accessoires en option vendus séparément.
ATTENTION
• Le produit n’est pas étanche à la poussière ni à l’eau. N’utilisez pas le
produit dans des zones très poussiéreuses ou dans lesquelles de l’eau
pourrait être renversée.
• Lors du nettoyage de la sonde, essuyez avec un morceau de chiffon
doux pour éviter d’endommager la sonde. Ne plongez pas le corps de
la sonde dans un liquide. N’utilisez pas de nettoyants abrasifs ni de
solvants volatils tels que la benzine sur la sonde.
Do not bring the probe near transformers, circuits with large currents, wireless
devices, or other objects emitting large electric or magnetic fields. Doing so may
produce inaccurate measurement results.

Operating Procedures
Preparation
1. Have the probe and a digital oscilloscope with a probe interface ready.
2. Insert the probe interface completely into the oscilloscope input, and
confirm that the BNC connector and interface pin are securely fastened.
You will hear the latch click when the connectors lock into place.
3. When you connect the probe to a digital oscilloscope with a probe
interface, the probe’s attenuation ratio and input coupling are set
automatically.
4. Attach any of the provided attachments or attachments that you
constructed to the probe head signal input terminals.
Note
If the digital oscilloscope does not detect the probe automatically, manually configure
the following settings on the oscilloscope.
• Set the probe attenuation ratio to 50:1.
• Settheinputcouplingto50Ω.

IM 701924-01E
Attachment Handling
Connect attachments that are suitable for the item that you want to measure
to the signal input terminals illustrated below. Select attachments from the
following list (see page 9 for attachment application examples).
• 5-cm pair lead
Can connect directly to a pin header or the item you want to measure. It
includes a damping resistor that takes pin header connection into account.
• 10-cm pair lead
Used in combination with a micro clip. It includes a damping resistor that
takes the micro clip into account. It is suitable for measuring relatively low-
frequency signals.
• Pin
The following four types are available. They are suitable for measuring
relatively high-frequency signals.
• Straight pin
• Angled pin
• Spring-type straight pin
• Spring-type angled pin
• A lead that you created using a kit
Create your own lead when you need a lead that is longer than the ones
included in the accessories, or when you want to prevent the lead from
coming loose from the probe head by using the retaining cover. For
instructions on how to create your own lead, see the next page.
Note
• The provided pair leads include the following damping resistors. These pair leads
can connect to a 0.64-mm square pin.

• For typical frequency characteristics of attachments, see appendix 1.

Positive signal

Negative signal
input terminal
GND terminal
Because the probe input is high impedance, the inductance from the probe
head to the circuit under test has a large effect on the measured results of high
frequency signal components. When measuring signals that include frequency
components of 100 MHz or higher, we recommend that you use the shortest
attachments possible for both the positive and negative input terminals.
Operating Procedures

Creating an Extension Lead
You can create your own extension lead using the accessory kit.
At the Circuit-under-Test End
1. Pass the lead wire through a heat-shrink tube for a contact.
2. Crimp or solder the lead wire’s core wire to the contact.
3. Cover the contact with the heat-shrink tube, and then apply heat with a
drier to fix the tube in place.
In step 2, you can insert a damping resistor between the lead wire and contact
as shown in the illustration below on the right.

6. Cover the flanged input pin with a heat-shrink tube, and then apply heat
with a drier to fix the tube in place.
Do not cover the section of the flanged input pin to the left of the broken
lines shown in the following figure with the heat-shrink tube. Make sure
that the diameter of the tube after shrinking is 2.0 mm or less. If the
maximum diameter exceeds 2.0 mm, the lead wire will not be able to
